IMPROVEMENT IN STREET AND TATIONINDICATORS The Schedule referred tointhese Letters Patent and making parl: of th same.

To all whom it may concern:

Be it known that we, Gnoncn A. Jenks' and J oHN J. Fawcnrcr, of Chicago,in the county of Cook land StateA of lllinois,'have vinvented anImproved Street-Indicator and Advertiser for Street- Cars and otherpurposes; and we do hereby declare that the following is a full andexact description thereof, which will enable those skilled in the art tomake and use the same, reference being had to the accompanying drawingand'letters marked thereon, making a full and true description, inwhich- Figure 1 vis an elevation of our improved streetindicator andadvertiser, the face-cap being removed to give a view of the mechanisminside.

Figurer 2, a face view of the device with the faceeap in position, 'aswhen in use.

f Figures 3 4 are elevations of the opposite ends of' the innerframe-work, &c.

Tile presentinvention relates to an improvement in indicating streetsinstreet-cars and other purposes', as showing advertisements and Itsnature consists ih the novel mechanism whereby that purpose isaccomplished, as the whole is hereinafter fully described.

1 A-represent a substantial case, having suitable ends, which isconveniently arranged to support the mechanism f or operating thelettered or gured belts F G, to show thelctters and figures thereon bothto passengers and to the driver, as shown by openings at B C, gs. 2 andl8, the opening 2 being for the drivers use.

.lhat part of the case at A is removable from part 1 for the convenienceof reaching the. mechanism -inside, and of manufacture.

Inside of that part of the case shown at A, and

fastened to the part A1, are metal end plates, K- K7, which support therollers and other devices hereinafter named.

A large central roller, M, has bearings in thel end plates K K', and toits shaft, on one end, is fixed a wheel, T', and to the other end aratchet-wheel N.

. The function of the wheel 1" is to rotate the roller M, which is donevby means of a bell-cord, U, passing over wheel T and through that partof the frame shown at 1, gs. 1 and 3.

The bellcord being within convenient reach of the conductor, the belts FG are readily carried over the rollers far enough at each pull of thecord U to bring the name of a street and an advertisement oppositey T',either one of said pawls being held closely tothe i ratchet-wheel h bymeans of a single curved spring, t y

1The rollers M H I are designed to turn in either direction, and, toaccomplish that purpose, a semidisk, m, is placed ina recess in theinner side of wheel T', and it is so acted upon by an eccentric, V',iig. 5, as to throw-either pawl y on from the ratchet h, and throw theother one in by. pressing against either prong 'of the spring t p.

The eccentric is operated by a crank, V, placed outside of wheel'T,figs. l and 3.'

This arrangement for reversing Athe movement ot' the rollers isvsnchthat a pull on the cord U. will give a direct forward movement to thebelts E Gr, and such that, when the eccentric V is'turned by crank V,the backward movement of the wheel T', by rubber spring S, will give abackward movement to said belts.

Stopsqr, 011 wheel Tf, and ka stop, z, on plate K shown by dotted lines,iig. 1, prevent wheel T from turning too far. A

The reversing being done at the end of theline, the last /streetindicated will be the rst one on the return trip.

Coil springs l H are placed inside of the rollers I H, andattachedbothto the shafts I' H'of the rollers and to the innerperipheries of the rollers, hold'the belts F G in proper position, bybeing wound up with the large roller, so that when the pawls garereversed, the springs will, of themselves, roll up the belts on thesmall rollers andkeep them tight.

To prevent the -springs I" H' from moving the belts when the cord U isnot operating them, a spring-lock,

X, is used, whose inner end catches into notches d d,

Sac., made in the periphery of a plate, C, attached to the roller, saidlock passing through the end plate K.

' To loosen the catch X, cams 'W W, attached tothe outer face of wheelT', are made to operate on another eamattached to the lock, as shown iniig. 1. To the opposite end of the journal of the roller M is attached aratchet-wheel, N, which. as the roller M 'H I, placed parallel with eachand having att-ached t-o one end a bell-hamn1er, P Q, E, by

rotates, 'operates a spring 2, will be rung at the means of which a.bell, D, iig.

' same time a street is indicated.

Twobelts are. used, as shown at fig. 8, overlapping each ot-her onroller as shownat fig `s. V 1 and 2.-

Clam. .e 4 lhe arrangement and combination of the rollers 'M other, themiddle roll being the largest, ratchet-wheel, N,

for ringing 'the bell D, and to the M, one belg having the names of astreet-s marked thereon, and the other advertisements,
